SULKY-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 242,134, dated May 31, 1881.

Application filed March 9, 1881.

city of Beloit, Rock county, and State of Wiscousin, have invented a certain new and usefullmprovementin Sulky-Gultivators, ofwhich the following is a specification.

My invention relates to improvements in sulky-cultivators; and the object of my improvement is-to simplify the construction of the mechanism provided for operating and for better controlling the operation of the machine a while doing field-work, a compound and combined device being provided for that purpose, whereby, also, the operator has more convenient, easy, and perfect control of the drag-bars carrying the cultivator-plows and appurtenant mechanism, and also largely cheapening the manufacture of cultivators containing my newly-invented improvement therein. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of so much of an entire machine as is necessary for illustrating and showing the proper relation to and connection of my improvement therewith; and Fig. 2 is a detached view of a section of one of the vertical standards supporting the drag.

bars, having universal ball joints near the foot of each.

Similar letters refer to similar parts through out the several views.

The forked tongue A, transverse bars B O, angular brace b, and ratchet It show the ordinaryparts of the frame-work of asulky-eultivator, exclusive of the appurtenant parts hereinafter described, which contain my invention and constitute my improvement therein.

Letter E represents a vertical metal standard, its upper, end bolted to the frame A, its foot being supported by the brace b, and provided near the lower end with a ball made solid thereon, (shown at Fig. 2,) which, in connection with the eye-socket i of the part D, constitutes a universal joint, upon which the dragbar H oscillates.

K is a vertical lever-bar, pivoted to the frame A at i 2', having a side lever, :10, rigidly joined thereto, and oscillating laterally therewith upon the pivot, at i 2'. The foot of the vertical lever-bar K is provided with a universal ball- (Model) joint similar to that upon the standard E hereinabove described, which together constitute a compound leverage and a compound balljoint device, whereby the drag-bars H are raised and lowered by means of actuating the hand-lever L and foot-levers 9, (shown at Fig. 1,) but the arrangement and functions of which are hereinafter next particular] y set forth. The front end of the foot-levers g is pivoted to the frame A at P, and is connected by a chain, at, at a suitable point for leverage, to the side lever, :0.

The hand-lever L is pivoted to the vertical lever K at m, the side lever, 00, forming a fulcrum for the lever L, which also is provided on its inside with a suitable pawl for engaging with the-ratchet R, for holding it in the proper position.

Now, it will be seen and plaiiily understood that by depressing either the hand or foot levers the cultivator-plows upon the drag-bars will run at any desired depth, or may be raised entirely out of the ground by the operator from his seat upon the machine, and of course the drag-bars and plows will be lowered to the ground by their own gravity when pressure is removed from the levers.

The drag-bars will, as usual, be suitably connected at their rear ends, and will be properly swayed and guided laterally by the feet of the operator when at work, and will also be provided with necessary appurtenant usual dcvices to prevent injury to the growing corn.

The device D is made of metal, in two parts, secured together by a suitable screw or bolt, and bolted to the fore. end of the dragbars H, as shown.

It will be seen that by means of my improve ment the drag-bars may be controlled wholly by the feet of the operator, or by the hands and feet alternately, as most convenient and easy, as preferred; and it will also be seen that by means of my improvement much of the usual complicated mechanism employed to operate the cultivator is rendered unnecessary and has been dispensed with; that the construction and arrangement of the operating mechanism are much cheapened and simplified, which is a cardinal principle lying at the very foundation of all branches of manufacture, and which, iii general, is believed to be a very important improvementlin this class of machines, and is thechief merit claimed for my invention.

My improvement herein consists, chiefly, in the peculiar construction and arrangement of the vertical metal standard E with the balljoint thereon, as shown, the device D, the vertical lever K, side lever, x, with ball-joint, as shown, foot levers 9, chain couplimg 1 as shown, and hand-lever L, all as shown and described.

It will be observed that only one side of the machine is illustrated and shown in the drawings.

I am aware that prior to my invention sulkycultivatorshave hren constructed and provided With hand-levers connected with other mechanism for operating the cultivating devices. I
